Method for producing reflection sheet lampshade

Abstract

A manufacturing method of a reflector plate lampshade is disclosed. A plastic material with reflection ray characteristic is heated to soften the structure thereof, plastic molding is carried out by a rolling method to manufacture the reflector plate lampshade, by carrying out directly plastic molding process on the plastic material with reflection ray characteristic, the reflector plate lampshade is manufactured, thereby quickening production and saving cost.

Description

technical field [0001] The present invention relates to a manufacturing method of a reflective sheet lampshade, in particular to a manufacturing method of directly applying a rolling method to a plastic material with the property of reflecting light to form a reflective sheet lampshade. Background technique [0002] Cold-cathode lamps are mainly used as backlights for scanners and optimized Liquid Crystal Displays (LCD for short). Products that are also used for LCD backlights also have light-emitting diodes (LEDs for short). Due to various backlights Each has its advantages and disadvantages in terms of luminous quality, luminous characteristics, and production cost, and the size of the LCD panel used varies. For example, the LED luminous brightness is darker and the luminance cost is higher, and it is mainly used in small-sized panels; while the current mainstream LCD application products cannot emit light by themselves, but must be separately installed with light source c...

Problems solved by technology

[0005] However, there are problems in actual use. When the raw material of the lampshade is stamped and formed, the angle of the lampshade produced may not be uniform due to uneven force, resulting in poor reflection effect, and it is more difficult to develop molds for long workpieces. Difficult, moreover, when coating the reflective layer, the coating of the reflective layer may be uneven or the material of the reflective layer and the material of the lampshade itself may not fit each other, which will affect the reflection and light-gathering effect of the reflective layer. Complicated production steps not only have high production costs but also cannot control the quality, which is a problem to be solved. Therefore, the existing technology has the following disadvantages:

[0006] 1. High cost;

[0007] 2. The production process is also relatively complicated;

[0008] 3. Unable to produce longer workpieces;

[0009] 4. The coating quality of the reflective layer is not easy to control
